These records can be helpful to identify authorized mail servers. An MX record is sometimes called an MX entry, particularly in configuring mail servers.

If the serial number increases, the secondary name server will assume that the zone has been updated and initiate a zone transfer. A text TXT record can store any type of descriptive information in text format. For example, network antivirus providers can use TXT records to send and receive information. Subsequently, SPF helps prevent spammers from sending emails on behalf of your domain. Precisely because it can store anything, TXT records can also hide malicious commands.

As a result, that can make them attractive to cybercriminals conducting DNS tunneling. The BlueCat platform provides powerful capabilities to monitor and manage your DNS traffic and configurations.

Through a single pane of glass interface, you can manage, visualize, organize, filter, and monitor every DNS record query on your enterprise network. Surprisingly, most enterprises never analyze their DNS data for cyber threats. We like to call it taking a DNS Dumpster dive. Seven in 10 enterprises struggle to realize the full value of their cloud investments. New research by Enterprise Management Associates explains why and how to change that. One of the first stumbling points for new users is learning to identify zones and records.

All of a sudden there are dozens upon dozens of complicated acronyms and indecipherable names. DNS records are single entries that give instructions on handling received requests.

They only provide an initial validation of the information before passing it on to zones. Zones, then, are custom-purposed record systems that handle specific and non-standard requests. Think of it like a basic filtering system; records gather all the information and sort it to individual zones for processing.

There are dozens of types of DNS records and zones. Each one handles its own type of information to help streamline the DNS processing for maximum speed. You might see some or all of these zones listed in your domain registrar. Records have a few subsections you can manage and edit yourself inside your domain registrar account, at any time. These include altering the record type, switching between zones, changing the subdomain where the record points to, and altering the time to live TTL value.

A record name is the descriptor for your domain entry that effectively creates a subdomain for the record. Since you added this to the record name, the connection will resolve what you told it to. One of the most common alterations people make to the record name field is differentiating between base URLs and URLs with a prefix.

This means the other record will refer to the value of the base form before resolving. When a nameserver is queried for a DNS record, it first checks the TTL value to see if it has delivered the same record within the listed time period. Otherwise, the lookup queries the servers for updated information. Think of TTL as a pause button. Note that setting a TTL too low can cause significant slowdown to your site.
